Keck Observatory in Hawaii and the Very Large Telescope in Chile to follow up on 77 of the 5,000 candidate lenses.
The lenses are typically at higher redshifts than most previously known lenses, meaning that astronomers can see deeper into the universe with them.
The algorithm's 88% success rate in finding new lenses means there are now potentially thousands of new lenses for astronomers to choose from, though Tran said the team's aim was more modest. .The average redshift of the lenses is 0.58, which corresponds to a distance of about 5 billion light-years, whereas the faraway objects that are being magnified by the lenses are typically at redshifts of about 1.92, meaning their light set out about 10 billion years ago.The lenses therefore provide promising targets for follow-up with observatories such as the Hubble Space Telescope and the James Webb Space Telescope!
